IMPROVEMENT IN PRESSES.

Specilication forming part of Letters Patent No. 56,588, dated July 24, 1866.

To all inkom it may concern:

Beit known that I, J AMES A. McGrLLIvRAE, of Dyer, in the county of Lake and State of Indiana have invented a new and Im )roved Beater-Press; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanyingdrawings, forming part of this speoiiication, in which- Figure l is a side sectional view of my invention, takenin the line w w, Fig. 2 5 Fig. 2, a plan sectionalview ofthe same, taken in the line x x', Fig. l; Fig. 3, a vertical section of the windlass, taken in the line y y, Fig. 2.

Similar letters of referenceindicate like parts. This invention relates to a new and improved press for compressing substances for baling,

and may be considered as an improvement on a press for which Letters Patent were granted to me bearing date January l0, 1865.

The invention and improvement consist in a novel construction of the press, as hereinafter fully shown and described, whereby great strength with durabilityis obtained, simplicity and economy in construction, and a uniform adjustment of the levers and platen at the termination of the upward movement of the latter. V

The invention also consists in a novel construction and arrangement of the windlass and tripping apparatus, whereby several advantages are obtained, as hereinafter set forth.

A represents the framing of the press, and B the press-box- The framing is composed of four uprights, a, the side pieces, b b, slotted at their lower ends to form spaces c for the levers C to work through. The side pieces, b b, are solid, and extend the whole width of the press-boX, rendering the latter very stiff and firm at its ends or narrow sides, and effectually preventing all springin g out of said ends or sides under the pressure of the platen D.

The uprights a are boltedor otherwise secured to the upper ends of the side pieces, b b, and the press-box is provided with the usual doors E E at opposite sides, and planked below said doors. This is a very simple and economical mode of constructing the framing, rendering the latter very stiff and rm.

The framing stands on two parallel sills, F F, the lower ends of the feet, formed by slotting the lower ends of the side pieces, b b, being framed into said sills. Each sill, F, at its upper surface, between the feet of the side pieces, b b, is elevated, as shown at d, and the ends of these elevated portions are made inclined, as shown clearly in Fig. 1 at e.

The upper ends of the levers O G are connected by pivot-bolts e to the under side of the platen D. The lower ends of these levers are provided with rollers H, one at each side, and these rollers work on the sills F F. Each lever G has a pulley, I, attached to it by a bracket, f, and around these pulleys I and a iiXed pulley, J, attached to one of the sills F, the windlass-rope K, which operates the levers C, passes. The inclined ends e serve as stops for the lower ends of the levers O, and cause both of said levers to be brought to a oorresponding position when the platen reaches the termination of its upward movement; for, if the rollers T:I of one lever should reach the inclined ends e of the elevated parts d of the sills in front of them before the rollers of the other lever reach the other ends c the former levers will of course be stopped, and the other lever brought up against the inclined ends in front of them, and both levers have the same or a corresponding position, and the platen a horizontal position. This improvement, though simple, is important and insures the proper working of the levers G.

L represents the beater, which is arranged so as to serve the purpose of a head-block when the platen is raised under the movement of the levers C. This beater, when used as such, is operated by a rope, M, which passes over a pulley, N, on the top of the framing, and down underneath a pulley, f, at one end of one of the sills F, and is attached to a slide, O, fitted loosely on a liange, g, of a wheel, P, on the windlass-shaft Q, said slide being secured in position or on said flange by an iron rim, h. (Shown clearly in Fig. 3.)

The rim t' of the wheel P is of wood, and it is connected to the shaft Q by a spider, R, composed of metal arms j, strengthened by a rim, k, as shown clearly in Fig. 2.

On the top of the rim there is secured, by a joint, l, a metal bar, S, which serves as a means to move the slide O and raise the beater when turned down on the rim t', said bar S, when down on the rim t', being between metal cleats m m, attached to the upper surface of rim t. This bar S is raised free from the slide 0 at every revolution of the wheel P, in consequence of its outer end4 coming in contact with an inclined curved bar, T, attached to the framing of the Windlass, and the slide O being` thus set free, and at the time the beater reaches its highest point, the beater, of course, falls by its own `gravity.

The operation of the beater is not novel, but the hinged or jointed barS is novel and important, as, by simply turning back said bar the beater in a moment is rendered inoperative, While the windlass is allowed to rotate, in order to operate or raise the platen in order to compress the substance previously beaten in the press-box.

The rope K, which operates the levers G G, is attached to a drum, U, placed loosely on the Windlass-shaft Q, and connected with the Wheel P by means of a slide, V, which, when shoved down, will en gage with one ofthe arms j ofthe spider R. To release or detach saiddrum U from wheel P the slide V is raised, so that its lower end will be above or free from the arms j of the spider.

The metal rim h is necessary, as a wooden one would soon become Worn Linder the action oi the slide 0.

Having thus described my invention, I claim as new and desire to'secure by Letters Patent- 1. The connecting` of the rim t' of the Wheel P with the shaft Q, of the Windlass by means of the metal spider It, in combination With the loose drum U on shaft Q,-and the` slide V, or l an equivalent fastening, to engage with the armsj ot' the spider, substantially as set forth.

2. The attaching of a metal rim, h, to the liange g of Wheel P, in combination With the slide O, substantially as and for the purpose specified.

3. The bar S, attached to the rim i of Wheel P by a joint, Z, in combination with the cleats m m on said rim, the slide and the inclined curved bar T, attached to the framing of the Windlass, substantially as and for the purpose set forth.

The above specification of my invention signed by me this 16th day of September, 1865.
